2 . On July 24, 1916, a natural gas explosion trapped 32 men working in a tunnel 250 feet below Lake Erie. The first rescuers who entered the tunnel were _________ by gas, and for hours no one else dared to enter the suffocating (窒息的), _________ deathtrap.
Then, late that night, someone had an idea: _________ Garrett Morgan and his new invention. Garrett Morgan was a successful factory owner in Cleveland. The son of freed slaves and the seventh of 11 children, mechanically minded Morgan had opened his own sewing machine shop, which he soon _________ to a tailoring factory with 32 employees.
In the early 1900s, factory buildings were crowded and untidy. They were often made of wood, with no fire escapes. Fire could cause serious _________. Concerned about his employees, Morgan _________ with a “safety hood” (头罩) that would allow the wearer to _________ despite a fire’s poisonous smoke.
Morgan knew smoke rises during a fire. Therefore, he created a heat-resistant hood with a long tube reaching to the floor. Wearing Morgan’s hood, a firefighter could breathe the _________ air near the ground. Morgan lined the breathing tube with a sponge-like material that was wetted before use to ___________ the air. A second tube was designed to __________ exhaled (呼出的) air.
Called to the scene on the night of the tunnel explosion, Garrett arrived with samples of his safety hood. Still in their nightwear, he and his brother Frank put on the hoods and bravely entered the tunnel. It was a dangerous __________ of the invention, but they saved two lives and __________ four bodies before officials closed the __________. Morgan knew that more lives might have been saved if he had been called sooner.
The daring __________ made Morgan famous and brought requests for safety hoods from fire departments around the country. But his greatest __________ was knowing that his invention would now save more people.
